| 摘 要： | 基于CFD方法,建立了数值波浪水池,就Wigley-Ⅲ船模在不同航速下摇荡运动辐射问题进行了数值模拟,给出了一种求解航行船舶辐射运动的水动力系数的方法.计算分析了船体相关模态运动的附加质量与阻尼,与势流理论结果、DUT(Delft University of Technology)的试验数据进行了比较,吻合良好.对比和研究表明,本文的方法比实验更易实现和控制,能细致描述船舶周围的流场,在船舶水动力性能的分析预报等方面具有广阔的应用前景.

| Abstract: | advancing at different forward speeds are carried out in the numerical wave tank,which is established based on CFD method.An approach to estimate and analyze hydrodynamic added mass and damping is outlined to deal with the measured forces acting on vessels.Comparisons of present results with the corresponding ones of potential flow theories and experimental data from Delft University of Technology are conducted,which show that they are in good agreement.Compared with the physical experimental method,present... |
